ESP8266
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

ESP-01/ESP-01S Breadboard Adapter

This is a breadboard adapter for the popular ESP-01 model of the ESP8266 serial-to-WiFi transceiver module.
As ESP-01 Pin arrangements are not breadboard friendly and are not labeled, which makes it little inconvenient for rapid prototyping.This breadboard adapter will help you to make
prototyping with esp-01 module much more easier.
This breakout conveniently offers clear pinout silkprint on top and will nicely fit your prefered breadboard.
Last but not least, we added a 0.1µF decoupling capacitor so the ESP-01 will always run smoothly and without a hitch.
